This syllabus outlines the essential ES6+ JavaScript features needed for React and Node.js development, covering everything from variable declarations to modern asynchronous patterns.

• ES6+ introduces key features like let/const, arrow functions, template literals, and classes that improve code clarity and reduce bugs.
• Asynchronous programming is handled through Promises and the async/await syntax, which simplifies working with tasks like API calls.
• Data manipulation is easier with the spread operator, rest parameters, destructuring, and the Map object for flexible key-value storage.
• Code organization is supported by modules for reusing logic across files and Symbols for creating unique object identifiers.
• Modern patterns include optional chaining, nullish coalescing, and default parameters for writing safer and more concise code.
